Which chamber of the heart sends deoxygenated blood to the systemic circuit via the aorta?

The left ventricle is responsible for pumping oxygenated blood into the systemic circuit via the aorta. This chamber receives oxygen-rich blood from the left atrium, which comes from the pulmonary veins after the blood has been oxygenated in the lungs. When the left ventricle contracts, it generates the high pressure necessary to distribute oxygenated blood throughout the body.

It’s important to note that while the right ventricle pumps deoxygenated blood to the lungs via the pulmonary artery, the left ventricle directly deals with systemic circulation. The systemic circuit is responsible for delivering nutrients and oxygen to tissues and collecting carbon dioxide and waste products, which is why the function of the left ventricle is vital for overall body function.
